Decent Laptop

Hi.. I've had my 1200's and Vestax 05 Pro since 97 and haven't really touched them until recently. I wanted a DVS and decided to get the Denon DS1, which I love, but also wanted a portable controller as well, which I just got the DDJ-SR. Love it so far, but now want to have just a laptop for Serato. I don't have a laptop that meets the spec of Serato which is a Intel Core i5 processor. I have a chromebook that i use as a laptop and a small Centrino tablet. I didn't want to spend a whole lot on a laptop so looking for suggestions on how low of an i5 I can get away with. I was thinking of getting a Lenovo T-430 with an i5-3320 processor. I know this is a few years old, but only $250. Wonder if anyone has this laptop and if it's working fine or slow, etc.

Thanks for you help.
